Puppies separated from their litters cried all night long.
One is nearly eating and drinking us out of test tube and petri.
The exposition shows Brock in Mars leaving the dome to do research for 1800 hours. The disembodied voice double checks his food, water and other resources before Brock goes for scientific research.
Apparently, emotions are easily triggered by interactions with primitive beasts, like dogs.
The rising action shows Brock confronting the extinct dog. He moves closer but the dig scoots back but also glides toward Brock.
Brock came back to the dome with the little pup and everyone was very concerned. The lab crew told him to get rid of the endangered animal but Brock refused. He told them the advantages about keeping the pup and they agreed and decided to keep him and the pup isolated in the research lab.
And maybe, just maybe, where there are dogs, there are humans as well.
The scientists were suggesting to clone Brog and give one to everyone in the colony. There was some negativity thrown in there and little did they know the mic was on and Brock heard more than enough.
Brock made a divergent and faked feeling sick. The scientists backed off and just let Brock and Brog run through the dome. The disembodied voice didn't even stop him and Brog. They both just dashed through the gates and out the dome as Brog was jumping and leaping in joy.
Brock and Brog went to the same place where they met and Brock took off his suit and thought a choking sensation would occur but nothing happened and he was free. He seen Brog take a drink of the water(poison) than Brock followed and the water just tasted fine. Brock thought to himself maybe Mars healed itself.
